+# This script sets up a custom opkg installation system for the SDXLEMUR platform
+# The primary feed for this will be my feed and will be a combo of modified IPK files from multiple sources
+# opkg is from entware and expects /opt to exist
+# /opt will be setup as an overlay of lower / and upper /usrdata/rootfs-upper
+# Most likely several mount binds will be setup at / to point back to /opt the overlay
+# The real /lib/systemd will need to be able to be written to so we may bind that within /opt
+# In active development; will decide if the entware feed gets re added later
